Catalogs of entities

Provides views of latest publications, people, annotations, groups etc.

Note: existing views were refactored for more unified code, so the diffs are large in some cases, but insignificant (about, terms, privacy pages etc. due to removal of the unnecessary .simple class)
Well, yeah, this is what I did after I saw the comment to use spaces around the division sign (you later removed the comment). I can roll back the whole thing and just have the bounds check fix.
